ABSTRACT:
Compaction of friable or unconsolidated strata containing petroleum substance is obtained by increasing the mass of material above the reservoir, vibrating various earth strata and alternately raising and lowering the fluid pressure in the reservoir to yield a maximum reduction in porosity of the reservoir matrix material and thus to expel petroleum substance therefrom. Enlargement of well bore and extension thereof as by drilling lateral wells are contemplated as is the production of solid reservoir material and recovery of other solids which may be compacted by the above steps and be slurrified and caused to flow to a well bore.
